Quartz muaju, vim lawv cov nyhuv zoo nkauj, ua si ib lub luag haujlwm tseem ceeb hauv ntau thaj teb. Lawv cov ntawv thov nyob hauv qhov ntau ntawm cov siab - tech tas nrho, suav nrog cov khoom siv hluav taws xob, nrog rau kev sib txuas lus, thiab aerospace.
1.Qhaartz Crystal Oscillator
Ib Quartz Crystal Oscillator siv ib lub quartz siv lead ua raws li tus tseem ceeb ntawm lub zaus uas muaj resonant-}} select} Xaiv Circuit Court. Cov oscillator no tau tsim los ntawm kev slicing slicing ib quartz crystal rau hauv cov ntaub nyias nyias thiab txuas cov hlau hlau rau lawv cov chaw. Nws txoj haujlwm ua haujlwm yog ua raws li Inverse Piezoeltric effect: Quartz muaju vibred mechanically hauv qab ntawm kev hloov hluav taws xob. Vim tias txhua tus quartz siv lead ua muaj qhov tshwj xeeb ntuj lub ntuj ntau zaus, resonance tshwm sim thaum cov ntaub ntawv siv hluav taws xob ntais ntawv no zaus. Cov xeeb ceem no ua rau quartz muaju xaiv qhov siab zoo tshaj plaws rau high {5} precision resonant zaus. Quartz Crystal oscillators, vim lawv qhov kev ruaj khov zoo heev, nrog rau cov neeg siv hluav taws xob, suav nrog cov cim ntawm cov cim, thiab quartz moos.
2. Quartz Crystal microbalance
Quartz Crystal microbalance (QCM) yog qhov ntsuas uas siv cov nyhuv piezoelectric ntawm quartz crystal los ntsuas kev hloov pauv hauv electrode nto loj. Txij li nws cov lus qhia nyob rau hauv thaum ntxov 1960s, nws tau dhau los ua cov cuab yeej muaj zog rau nananegram- theem kev kuaj pom vim nws qhov siab heev. Nws lub hauv paus ntsiab lus ua haujlwm yog tias kev hloov pauv ntawm qhov chaw ntawm Quartz Crystal electrode lub teeb meem ntawm cov zis hluav taws xob ntawm cov oscillation Circuital. Tus txheej txheem no tau txheeb xyuas los ntawm cov khoom siv los ntawm cov khoom siv xws li khoos phis tawj kom tau siab- precision ntsuas tau. Yog li ntawd, ib quartz crystal microbalance ua lub luag haujlwm tseem ceeb hauv ntau daim teb, kev lag luam tshuaj, zaub mov, kev lag luam ib puag ncig, kev lag luam thiab tub rog.
3. Piezoelectric Biosensor
(1) piezoelectric immunosensor
Tus ua haujlwm ua haujlwm ntawm lub tshuab txhaj tshuaj piezoelensor yog txhawm rau txhim kho cov tshuaj tiv thaiv lossis siv cov tshuaj tiv thaiv affinity ntawm antigen thiab antibody. Thaum cov antigen lossis tshuaj tiv thaiv kom ntsuas tau nrog cov khoom siv tau zoo thiab ua tiav cov adsorption, thaj chaw loj heev ntawm cov siv lead ua ke yuav nce raws li. Qhov kev hloov pauv no tuaj yeem soj ntsuam los ntawm cov kev hloov pauv ntawm lub sensor, yog li txiav txim siab tus nqi ntawm adsorbed antibodody lossis antigen.
(2) Piezoelectric Gene Sensor
Lub ntsiab lus tseem ceeb ntawm Piezoelectric noob gene sensor rau kev pom DNA yog txhawm rau kho cov kev sojntsuam DNA ntawm cov chaw ua haujlwm DINE. Thaum cov DNA pom tau yog ntxiv rau nws, hybridization kev tiv thaiv tshwm sim rau ntawm lub nti kom tsim tau ob zaug- stranded DNA. Cov txheej txheem no yuav ua rau muaj kev nce ntxiv hauv cov crystal loj thiab kev hloov pauv hauv cov visoelastic nto. Cov kev hloov no tuaj yeem ntsuas los ntawm cov kev hloov pauv zaus ntawm cov ntsuas thiab kev tshuaj xyuas network.
